Hello,

You can ignore this email unless you use any of the Airflow https://wikitech.wikimedia.org/wiki/Data_Engineering/Systems/Airflow instances https://wikitech.wikimedia.org/wiki/Data_Engineering/Systems/Airflow/Instances#List_of_instances managed by the Data Platform Engineering team.

Since the recent Airflow upgrade to version 2.7.3 we discovered a regression that affects all of our instances. It's a small bug https://github.com/apache/airflow/issues/36206 but it means that since the upgrade users have been unable to add notes to any tasks. See: T352534 https://phabricator.wikimedia.org/T352534 for more detail.

In the short term, we have decided to implement a workaround, which is to create an *admin:admin* user for each Airflow instance. You can use this to log in if you wish to manage notes associated with your DAG run tasks, the login link is at the top-right of the Airflow UI.

As the ability to access each Airflow instance is currently limited to those with SSH access to the host, this change is not granting anyone any additional rights that they do not already have. It's merely an inconvenience, for which we apologise.

We have several longer-term options in mind, but I won't go into them here.

I have made a note of this configuration detail here, in case you would like to refer to it again:

Naturally, please feel free to get in touch if you have any queries or concerns about this.

Kind regards, Ben
